影片

使用非同步任務模型產生影片剪輯 - 提交提示、輪詢狀態、取得結果。

影片生成是非同步的：送出 prompt、收到 task id、輪詢其 status，再取得完成的片段。text-to-video、image-to-video 與參考模式都共用同一種 request 結構。

你可請求的時長、解析度與 aspect ratio 取決於所選的模型 — 請從 models endpoint 讀回它們，而非假設有一組固定值。

視訊生成在背景運行 - 沒有流渲染。流程始終是：建立任務 → 輪詢狀態 → 下載 MP4。任務將在 24 小時後過期。

1. 創建任務

提交任務並回傳 task ID。費用依時長 × 模型每秒價格估算，並在任務處理時結算。

視訊模型

…· live

Parameter	Type	Required	Description
model	string	Required	Video model ID. Use /v1/models and filter by output_modalities.includes("video").
prompt	string	Required	Scene description.
mode	string	Optional	"text" (default), "image" (animate a first-frame image), "reference" (style transfer from one or more frames).
duration_seconds	integer	Optional	Clip length. Range depends on the model — typically 5, 8 or 10 s. Defaults to the model's minimum.
aspect_ratio	string	Optional	"16:9", "9:16", "1:1", "4:3" — must be in the model's supported list.
quality	string	Optional	"480p", "720p", "1080p" — must be in the model's supported list.
input_images	array	Optional	[{ url? } \| { b64_json? }] — required for "image" and "reference" modes.

任何其他鍵（例如 seed、sound）都會原封不動地轉發給上游供應商——它們在此處不會經過驗證，且支援與否取決於模型。

    "model": "kling-1",

    "input_images": [{"url": "https://example.com/dragon.jpg"}]
  }'

回覆

Parameter	Type	Required	Description
task_id	string	Optional	Persistent task identifier. Use it on every follow-up endpoint.
status	string	Optional	"queued" right after creation.
model	string	Optional	Echo of requested model.
created	integer	Optional	Unix timestamp.
expires_at	integer	Optional	Unix timestamp after which the result is purged (exactly created + 86400).
progress	integer	Optional	0 right after creation.
cost_cents	number	Optional	Estimated cost for the job. Final billing is settled when the job is processed.

{
  "task_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
  "status": "queued",
  "model": "wan-2.6",
  "created": 1715000000,
  "expires_at": 1715086400,
  "progress": 0,
  "cost_cents": 320
}

2. 輪詢狀態

每 5-15 秒輪詢一次。任務通常在 30 秒至 4 分鐘內完成，具體取決於持續時間和模型。當狀態翻轉為「已完成」時，同一端點會傳回結果 URL。

GEThttps://api.airforce/v1/video/tasks/:task_id

Parameter	Type	Required	Description
status	string	Optional	"queued" \| "processing" \| "completed" \| "failed" \| "expired".
progress	integer	Optional	0–100 while processing.
result_url	string	Optional	MP4 download URL once status is "completed", set by the upstream provider. Valid until expires_at.
error	string	Optional	Failure message. Set (non-null) when status is "failed".
cost_cents	number	Optional	Cost for the job, settled when it is processed.

{
  "task_id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
  "status": "completed",
  "progress": 100,
  "result_url": "https://.../video.mp4",
  "model": "wan-2.6",
  "duration_seconds": 8,
  "expires_at": 1715086400,
  "cost_cents": 320
}

2b.串流進度（可選）

使用伺服器傳送事件流跳過輪詢循環。每次進度變更都會發出事件，並在任務處於最終狀態時關閉。與 GET 端點相同的有效負載形狀。

GEThttps://api.airforce/v1/video/tasks/:task_id/stream

event: state
data: {"task_id":"f47ac10b-...","status":"processing","progress":12}

event: state
data: {"task_id":"f47ac10b-...","status":"processing","progress":58}

event: state
data: {"task_id":"f47ac10b-...","status":"completed","progress":100,"result_url":"https://.../video.mp4"}

event: done
data: [DONE]

3. 列出並刪除

GEThttps://api.airforce/v1/video/tasks

返回您最近的任務（最新的在前）。對於儀表板呈現歷史視圖很有用。

回傳您最近的最多 100 個 task，最新的在前，格式為 { "data": [ ...tasks ] }。沒有查詢參數——請在用戶端進行篩選與分頁。

curl https://api.airforce/v1/video/tasks \
  -H "Authorization: Bearer sk-air-YOUR_API_KEY"

DELETEhttps://api.airforce/v1/video/tasks/:task_id

從你的歷史記錄中移除該任務記錄。

具冪等性——一律回傳 { "deleted": true }。這只會刪除您的歷史記錄；並不會另外清除已儲存的媒體。

成本和限制

每個視訊模型都會公開您可以讀取的功能元數據 /v1/models:

Parameter	Type	Required	Description
video_caps.aspect_ratios	array	Optional	Allowed aspect_ratio values.
video_caps.qualities	array	Optional	Allowed quality values.
video_caps.min_duration_s / max_duration_s	integer	Optional	Allowed range for duration_seconds.
video_caps.modes	array	Optional	Subset of ["text", "image", "reference"] supported.
video_caps.price_per_second_cents	integer	Optional	Cost = duration_seconds × this value.

Cost is estimated at creation and settled when the job is processed; failed or expired tasks are not charged.
Max 4 concurrent video tasks per API key.
Result URLs are pre-signed and stop working at expires_at. Download or copy the MP4 to your own storage if you need it longer.

端對端腳本

async function generateVideo(prompt) {
  const create = await fetch('https://api.airforce/v1/video/generations', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      model: 'wan-2.6',
      prompt,
      duration_seconds: 8,
      aspect_ratio: '16:9',
      quality: '720p',
    }),
  }).then(r => r.json());

  const { task_id } = create;

  // Poll until done.
  while (true) {
    await new Promise(r => setTimeout(r, 8_000));
    const task = await fetch(
      `https://api.airforce/v1/video/tasks/${task_id}`,
      { headers: { Authorization: `Bearer ${API_KEY}` } },
    ).then(r => r.json());

    if (task.status === 'completed') return task.result_url;
    if (task.status === 'failed' || task.status === 'expired') {
      throw new Error(task.error ?? task.status);
    }
  }
}
